Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: Two believers will meet at the gate of Paradise, one will be wealthy and the other poor; they will have been friends in the world. The poor one will be admitted into Paradise, and the wealthy one will be held back for as long as Allah wills. Then, when he is admitted into Paradise and meets the poor one, the poor one will say: O my brother! What kept you back? By Allah, you were held back for so long that I began to fear for you. He will say: O my brother! After you, I was kept at such a place that was very terrifying and unpleasant, and until I reached you, I sweated so much that if a thousand camels that eat the hamd plant came to drink it, they would have drunk their fill and returned satisfied.
